The Link Passed Every Check and Pointed at a 404

Описание и применение

Ссылка в биографии автора была некорректно вставлена, что привело к 404. Проверка, основанная на фрагментах, не обнаружила ошибку, но второй читатель выявил проблему. Были введены новые правила: проверять целый рендер, открывать ссылку и перезаписывать поля полностью.

Задача

A product link in an author bio was incorrectly appended, causing a 404 page, yet verification rules passed it as correct.

Результат

The incident revealed that fragment-based verification can miss errors between sampled fragments. New rules were created to verify whole rendered units, verify links by opening them, and rewrite entire fields instead of appending.

Рабочий процесс

• Append offer sentence to bio at caret position
• Verify start and end fragments of sentence
• Second reader reviews full card and detects splice and 404
• Rewrite entire bio field, select-all replace, save
• Re-read card and open link to confirm product page

Доказательства

The live link read …gumroad.com/l/qaxzzeither. A dead page.

Источник

The verification sampled the render instead of reading it. Start-of-sentence: present. End-of-sentence: present. Conclusion: correct.

Источник

Three clauses, now standing orders for any surface we touch: Verify the whole rendered unit. Verify the link itself, not its text. Rewrite whole fields; never append at an unseen caret.
